Hyundai Palisade. Repair procedures

•	Be careful not to damage the bracket when removing the rear corner radar unit.

Installation

Install the rear corner radar unit and bracket.

Tightening torque :

bracket : 0.82 - 1.17 kgf.m (8.1 - 11.5 N.m, 5.97 - 8.48 Ib-ft)

unit : 0.31 - 0.37 kgf.m (3.1 - 3.7 N.m, 2.28 - 2.72 Ib-ft)

2.	install the rear bumper cover.

Connect the negative (-) battery terminal.

•	Take care not to confuse left side (master) and right side (slave) unit when installing.

4.	Perform "Correcting the Rear Corner Radar Unit Angle" procedures.

5.	Perform "Rear Corner Radar Calibration" procedures.

Inspection

Correcting the Rear Corner Radar Unit Angle

After replacing the blind-spot radar unit or bracket, with the bumper removed, use the blind-spot radar unit correction tool set (special tool : 09985-3T500) to perform angle correction.

•	Perform the task on a level place.

•	Perform the task after checking the tire pressure.

2.	Attach a vertical plumb (special tool : 09958-3T010) on the hood, and lower the plumb (A) to the ground so that it passes through the center of the emblem.

3.	Marking the center point below the plumb (A).

4.	Attach a vertical plumb (special tool : 09958-3T010) on the trunk (or tailgate), and lower the plumb (A) to the ground so that it passes through the center of the emblem.

5.	Marking the center point below the plumb (A).

Marking the center of vehicle by a string.

1)	Pass the string through the bottom of the vehicle from the rear of the vehicle to the front and fix the string to the center point (A) of the front of the vehicle.

2)	Fix the string to the point (C) about 1.5 - 2m from the back of the vehicle so that it passes the rear center point (B).

Hyundai Palisade. Repair procedures

Mount the blind-spot radar unit fixing adaptor (special tool : 09958-3T080) on the blind-spot radar unit and fix the level laser (special tool : 09958-3T070).

Hyundai Palisade. Repair procedures

•	When with the blind-spot radar unit cover, remove the cover and then mount the fixing adapter (special tool: 09958-3T080).

Measure the angle (C) between the center line (A) of the angle measuring plate and the horizontal laser beam (B) using a digital protractor (special tool : 09958-3T090).

Horizontal Angle (C): 54° ± 3°

Hyundai Palisade. Repair procedures

Use a digital inclinometer (special tool : 09958-3T100) to measure the vertical angle of the blind-spot radar unit.

Vertical Angle : 87° ± 1.5°

Hyundai Palisade. Repair procedures

10.

Measure the horizontal and vertical angles of left and right blind-spot radar units. If the measured values deviate from the specified values, insert a washer between the bracket of the blind-spot radar unit.

Specified Values

Horizontal Angle : 54° ± 3°

Vertical Angle : 87° ± 1.5°

Hyundai Palisade. Repair procedures

11.	After checking and correcting the blind-spot radar unit angle, perform the blind-spot radar radar correction procedure.

Rear Corner Radar Calibration

1.	Rear bumper accident vehicles and vehicles that replaced rear corner radar units must perform rear corner radar unit alignment using Diagnostic tool.

2.	Connect the cable of Diagnostic tool to the data link connector in driver side crash pad lower panel, and turn on the Diagnostic tool.

3.	Select the 'S/W Management' and 'Car model'.

4.	Select "Blind -Spot Collision Warning" and "BSD Radar Calibration".

5.	Perform the "BSD Radar Calibration" procedure according to the Diagnostic tool screen message.
